To aZZ whomA t may concern.'

Be it known that l, RILEY E. LAnnnr, a citizen of the United States,residing at Enid, in the county of Garfield and State of klahonia, haveinvented certain new and useful improvements in Extracting rfools, etwhich the following is a specication.

rlhis invention relates to tools specially adapted for extractingbearings, sleeves, bushes, and other similar articles from their socketswhen the articles can only be reached from one end; and it consists inthe novel construction and combination or the parts hereinafter fullydescribed and claimed.

in the drawings, Figure 1 is a 'front view ci" a tool constructedaccording to this invention. Fig. 2 is a side view of the saine. F ig. 3is a section through portions or' the tool, taken on the line 3 3 inFig. 2, and showing the jaws separated a little. Fig. e is a.cross-section taken on the line 4.--4 in Fig. 3. Fig. 5 is a side view,and Fig. 6 is a plan view, of an abutment plate used in connection withthe tool.

Two levers 7 are provided, each having a handle portion 7. Lugs 8 areprovided at the middle portions of the levers, and the lugs of one leverare arranged to overlap or straddle the similar lugs of the other lever.Each handle portion 7 is arranged at an obtuse angle to the other ormain end portion of the lever to which it pertains. then the tool isclosed, as shown in Fig. 1, the handle portions 7 are widely separated,and the other end portions are substantially parallel to each other.These latter end po-rtions are channelshaped in crosssection, andterminate' in outwardly projecting wedge-shaped jaws 9.

The lugs S are pivoted to a nut 10 by pivots or screws 12, and alongitudinal extracting screw 1d is provided which works in the. nut 10and is arranged between the channel-shaped portions of the arms. Theouter end of the screw is pointed and projects between the jaws. Theother end of the screw has a head 16 tor revolving it, and 17 is a.short bar which is slidable in holes 1S in the head, and enables it tobe turned so as to exercise considerable pressure.

A screwthreaded rod 2O is pivoted to one of the handles 7 and projectsthrough a slot 21 in the other handle, and is arranged Serial No.685,231.

crosswise ot the screw 14. A spherical socket 22 is formed at the end ofthe slot 21, and a thumb-nut 24 is screwed on the rod 20, and has aspherical projection 25 which works in the socket 22. The slot 21enables the rod to be slid ont ci enga-gement with the handle, whendesirable, without removing the nut 2a from the rod.

in order to remo-ve a bush,.or similar ar ticle, from a socket when oneend only of the bush is exposed, the tool is inserted in the open end ofthe bush, and the jaws 9 are forced apart by hand or by thescrewthreaded rod 20 and thumb-nut 24 so that they pro-ject beyond theother end of the bush between it and the bottom of its socket, andengage with the bush. The extracting screw is then revolved so that itspointed end bears against the botto-ni of the socket, and moves the bushlongitudinally. lVhen the bush nioves freely the handle portions aregrasped, and the bush is pulled out. When the bottoni of the socket hasa hole in it so that a bearing for the screw cannot be had, an abutmentplate is placed over the hole, for the end of the screw to bear against.These abutment plates are oit any convenient size and shape, and theplate 30 has a recess 31 for the pointed end of the screw to engagewith, and a convex surface 32 which tits against the edge. of the holein the bottom of the socket.

Vvlhat claim is:

l. An extracting tool, comprising two arms having overlapping pivotedlugs at their middle portions, each arm having a handle portion arrangedat an angle to its main portion and having a jaw at the tree end of itsmain portion, a nut pivoted to and between the said lugs, and anextracting screw working in the nut and projecting between the mainportions off the arms,

2. An extracting tool, comprising two pivoted arms having jaws at oneend and diverging handle portions at the other, a nut pivoted betweenthe arms, and an extracting tool working in the nut, one of the saidhandle portions having a slot in its tree end and a spherical socket, ascrewt-hreaded rod pivoted to the other handle portion and slidable inthe said slot, and a nut screwed on the said rod and having a sphericalprojection which engages with the said spherical socket.

3. An extracting tool, comprising two arms having lugs et their middleportions which overlap each other, a nut, pivots for the said lugssecured to the said nut, and an 5 extract-ing screw and projectingportions of the arms,

Working iii die said mit` between the adjacent `end.

said end portions being channel-shaped in oross-seoton to clear Intestimony whereof I have aixed my signature.
